The fan is controlled by a room light switch. It is not included in the delivery package.

The fan is controlled by the built-in pull cord switch V. Not applied in case of ceiling mounting.

Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may connected to the same controller. Speed controllers can not be connected to the fans with T, TH, TP, VT, VTH modification.

Automatic:

By the electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately.

By the timer T (the built-in run-out timer enables the fan operation within 2 to 30 minutes after the fan switching off).

By the humidity sensor and timer TH (if the humidity level in the room exceeds the sensor threshold adjustable value within 60-90% the fan switches automatically on and operates until the humidity level drops to the standard level, after that the fan continues operating within the time period according to the timer setting, then shuts down).

By the motion sensor and the timer TP (in case of motion detection the fan switches automatically on and operates within the set time period from 2 to 30 minutes. The motion sensitivity area is up to 4 meters and the maximum detection angle is 100°.

MOUNTING FEATURES

The fan is mounted directly into the ventilation shaft.

Flexible duct application is recommended in case of remote location of the ventilation shaft. The air duct is connected to the fan exhaust flange through a clamp.

The motor is equipped with ball bearings for long service life (appr. 40 thousand hours) and fan mounting at any angle. The bearings are maintenance-free and contain enough grease for the entire operating period.
